Adult Swim (Stylized as [adult swim]) is an American adult-oriented nighttime programming block of the basic cable network Cartoon Network that is programmed by its in-house production studio, Williams Street. Marketed as a separate network for ratings purposes, Adult Swim currently broadcasts nightly from 9 p.m. to 6 a.m. ET/PT.
Debuting in 2001, Adult Swim serves as the nighttime identity of Cartoon Network, and it was established as alternative programming during late night hours when Cartoon Network's primary target audience, children between the ages of 7 and 15, would normally be sleeping. In 2005, Adult Swim was granted its own Nielsen ratings report from Cartoon Network due to it targeting a separate demographic. The block features stylistically varied animated and live-action shows, including original programming, syndicated series, anime, original video animations, and short films with generally minimal or no editing for content.
Adult Swim has frequently aired adult animation features, mockumentaries, sketch comedy, and pilots. The block's shows are known for their sexual themes, frank sexual discussion, nudity, strong language, and graphic violence. Many of its programs are esthetically experimental, transgressive, improvised, and surrealist in nature. Adult Swim has contracted with various studios known for their productions in absurd and shock comedy.
As with Cartoon Network, Adult Swim's reach through various services totals 94 million American households.
The Canadian version of Adult Swim launched as a late-night programming block on Cartoon Network Canada on July 4, 2012; and as a standalone channel on April 1, 2019. Rick and Morty initially premiered on Adult Swim Canada on January 10, 2016.
